 The GNU compiler suite has been update to version 10.0.1. See the http://gcc.gnu.org/gcc-10/changes.html[upstream documentation] for user visible changes. Packages in Fedora 32 have been rebuilt with the new version of the compiler.
 
 === New Features and General Improvements:
 
-
 *    New built-in functions:
 **        The `__has_builtin` built-in preprocessor operator can be used to query support for built-in functions provided by GCC and other compilers that support it.
 **        `__builtin_roundeven` for the corresponding function from ISO/IEC TS 18661.

+== mpfr version 4.0.2
 
+Fedora 32 provides the GNU MPFR library version 4.0.2. Notable changes include:
 
+* mpfr now supports shared caches for multithreaded applications, thereby reducing memory usage.
+* Improved caching: a minimum of 10% increase of the precision is guaranteed to avoid too many recomputations, thereby reducing CPU usage.
+* A small-precision `mpz_t` pool is used to reduce the number of memory allocations, thereby reducing CPU usage.
+* Several functions are now faster; e.g., `mpfr_add`, `mpfr_sub`, `mpfr_mul`, `mpfr_div`, `mpfr_sqrt`, `mpfr_set_d`, and `mpfr_get_d`.
+* The `mpfr_div_ui` function could produce incorrectly rounded results in mpfr 3; the bug has been fixed in mpfr 4.
